Preliminary
Each I/O bank can support multiple standards with the same V
input and output pins. For example, when V
support LVTTL, LVCMOS, 3.3-V PCI, and SSTL-3 for inputs and outputs.
LVDS I/O Pins
A subset of pins in all four I/O banks supports LVDS interfacing. These
dual-purpose LVDS pins require an external-resistor network at the
transmitter channels in addition to 100-Ω termination resistors on
receiver channels. These pins do not contain dedicated serialization or
deserialization circuitry; therefore, internal logic performs serialization
and deserialization functions.

MultiVolt I/O Interface
The Cyclone architecture supports the MultiVolt I/O interface feature,
which allows Cyclone devices in all packages to interface with systems of
different supply voltages. The devices have one set of V
internal operation and input buffers (V
